A comparative study of middle ear evaluation by otomicroscopy and otoendoscopy in cases of chronic suppurative otitis media
Purpose: Chronic suppurative otitis media (CSOM) is one of the common causes for hearing impairment and disability. Despite continuous technical improvements, the basic optical principles and their limitations have remained the same over the past three decades. This study was aimed at visualizing an...

ENT, Amala Institute of Medical Sciences, Thrissur-680 555, Kerala, India.Purpose: Chronic suppurative otitis media (CSOM) is one of the common causes for hearing impairment and disability. Despite continuous technical improvements, the basic optical principles and their limitations have remained the same over the past three decades. This study was aimed at visualizing and evaluating the middle ear structures with the aid of an otomicroscope and 0, 30 and 70 degree-angled endoscopes in cases of chronic suppurative otitis media. Methods: In this prospective study, 100 patients (63 males and 37 females) above the age of 10 years with CSOM were subjected to both otomicroscopy and otoendoscopy. The visualizations of middle ear structures were compared and statistically analyzed. Results: Middle ear structures were better evaluated with 30 and 70 degree endoscopes (p < 0.05) than with a microscope. No statistically significant (p > 0.05) advantage of endoscopes over microscopes was detected in examining middle ear mucosa. However, the microscope was better than a 70 degree endoscope in visualization of the mouth of the retraction pocket. Conclusion: Endoscopy provided a significantly better visualization for all the parameters studied versus a microscope. It is desirable to study the role of the endoscope in more cases of unsafe CSOM and also intraoperatively.
